\(\Leftrightarrow\dfrac{2\left(x-1\right)+3\left(3x-5\right)}{6}+\dfrac{2x-5x+3}{9}=\dfrac{1}{2}\)
\(\Leftrightarrow3\left(2x-2+9x-15\right)+2\left(-3x+3\right)=9\)
\(\Leftrightarrow3\left(11x-17\right)+2\left(-3x+3\right)=9\)
\(\Leftrightarrow33x-51-6x+6=9\)
=>27x-45=9
=>27x=54
hay x=2
\(\Leftrightarrow\dfrac{2\left(x-1\right)+3\left(3x-5\right)}{6}+\dfrac{2x-5x+3}{9}=\dfrac{1}{2}\)
\(\Leftrightarrow\dfrac{2x-2+9x-15}{6}+\dfrac{3-3x}{9}=\dfrac{1}{2}\)
\(\Leftrightarrow\dfrac{11x-17}{6}+\dfrac{1-x}{3}=\dfrac{1}{2}\)
\(\Leftrightarrow\dfrac{11x-17+2-2x}{6}=\dfrac{3}{6}\)
\(\Leftrightarrow9x-15=3\)
\(\Leftrightarrow9x=18\Leftrightarrow x=2\)
